fix: improve typescript defs

[43081j]

fixes #356

i need some help with the overloads here i think.

you can see the strong types now mean a bunch of tests need to cast things too... im not sure there's a clean way to type the callback function strongly and not have to do those casts. the compiler is right: the result could be undefined if there's an error.
